It seems to me that you are probably suffering occasional corruption,
either due to a hardware problem (VIA chipset, IDE drive or controller, perhaps)
or a software bug in the IDE driver or MD layer.
Ext3 does a *lot* of sanity checks (thank you Stephen!) and seems to
trap problems much more quickly than ext2 or some of the other file
systems. That's a *good* thing.
I didn't see you refer to what is running on the system. Is /var getting
a lot of activity? Depending on what you are running, some log files may
be fsync()'d after every log write, which can put more pressure on
/var than the other filesystems. / and /usr are generally static,
/home may or may not be, depending on what you are doing.
